London is in for a soaking this weekend with wind and rain set to sweep the capital.
Temperatures are predicted to plunge to a chilly six degrees as the first real rain of the Autumn arrives.
Saturday is due to see the worst of the weather, with conditions improving slightly on Sunday, before temperatures drop again next week when parts of the UK have been warned to expect gale force winds.
A Met Office spokesperson said: "After a bright start in places, outbreaks of rain will spread from the west. The rain will become heavier and more persistent during the afternoon before it finally clears. "
The spokesperson said Sunday was due to be "dry and breezy with some sunshine at times on Sunday", but warned that by Tuesday the weather would become unsettled again, with more rain on the way.
Richard Chapman, spokesman for The Weather Network, added "The final week of October has a distinctly more unsettled look to it compared to much of the month so far, as low pressure becomes the dominant feature of our weather, often centred toward the west, and may be slow moving over a few days.
"Rain spreads east to many areas overnight into Saturday, turning heavy for a time, accompanied by strong and gusty winds.
"Going into next week, precise day to day details will be tricky at this stage, but expect frequent periods of heavy rain throughout the week."
